u HR-150DT Instrument Description:

Hardness is one of the important criteria of the mechanical functions of materials, and the hardness test is the important way to judge the quality of the metallic materials or parts.
As the metallic hardness has mutual correspondent relations with other mechanical functions, the majority of the metallic materials can calculate the other mechanical functions such as the strength, the fatigue, the evolutionary change and the degree of being worn out,which can be approximately inferred from the hardness shown by the test.
HR-150DT analogue gauge resolution is 0.5HR, it is useful to improve the reading accuracy than traditional 1HR resolution
HR-150DT dwell time from 1to 60s can be setup by the “time key” on the panel , it is much convenient than the setup on the manual hardness tester.
HR-150DT loading, dwell and unloading is buffering by oil pump, it eliminate the operator’ s tiredness.
HR-150DT force knob adopts the metal material to replace the plastic, it improves the instrument using-life a lot.
HR-150DT loading, dwell and unloading is buffering by electronic motor automatically ,doesn’t need the operator to handle it ,it eliminates the human operation error maximum.

HR-150DT indenter protector is available to improve the using lifetime of indenter.
